Why take this course?

Are you a software developer? If not, are you aspiring to be one? If you answered yes, then I have good news for you!

Dependency Injection is the cornerstone of good, decoupled software engineering principles. And this course is your ultimate guide to the latest Contexts and Dependency Injection (CDI 2.0) standard on the Java Platform.

You will learn how the Java dependency injection framework - CDI - helps you write better code through the provision of

Powerful, extensible and well defined contextual lifecycles for components
A mechanism for decoupling application components through a typesafe event API
Typesafe interceptors for altering the behaviour of components at runtime
A well defined Qualifier system for easy isolation of beans
A Producer mechanism of converting almost any valid Java type to a CDI managed bean
A Stereotype system to group together common architectural patterns
Bindings for using business components on the web tier of your applications through Expression Language

All these and more will be covered in an exciting way through a mixture of detailed theoretical explanations and practical code samples, all the while using modern pedagogical means to keep you engaged and help you absorb your new knowledge. You are encouraged to be an active student by asking questions, participating in group discussions and helping your fellow students.

If you have ever wanted to write clean code, this course is your best guide for that. You will pick up valuable tips along the way from your instructor's years of experience. This course will cover CDI 2.0 in detail, as well as equip you with the theoretical underpinnings of Java EE.

Dependency Injection for Java Developers will cover

What Java EE is
How Java EE is evolved through the JCP
What a JSR is
What Reference Implementation is
How to contribute to the advancement of Java
Contexts and Dependency Injection
Good software engineering principles and more

Dependency Injection for Java Developers is packed with so much that by the end of the course, you will feel confident to use your new found knowledge to help you write better, readable, maintainable and long lived software.

The course is for very beginners. I expected more "advanced" topics to be explained, like programmatic bean resolution with TypeLiteral/AnnotationLiteral, some more deep dive into the bean manager and so on. That explain the missing half star. Now, the other 4 and 1/2: 3 and 1/2 are because the trainer is very clear (even if he tends to be a bit repetitive but I think that sometimes it's a plus) and the topics coverage is good to get the grasp over CDI and be efficient. The last star is for sections 9. It's the first time I find someone who can clearly explain the very beginning steps of running tests with JUnit and Arquillian. Maybe a bit more "training on the job" would have been appreciated but still definetely a course that I would recommend to any J2EE (or now Jakarta EE) beginner.

As I have many experiences with the Google Guice DI framework, I just wanted to know how the different framework works. This course perfectly met my expectations.

At first, I had a bit of a problem with the presenter's English accent (it is different from my own) but once I got the feel for it I learned a lot. The course is really excellent and the explanations are clear and concise. I feel like I understand CDI really well now, whereas before it was difficult to get a clear idea of what it was from other sources. Thank you!

Ola, Não é o que esperava, poderiamos ter primeiramente opçao de linguagem. O assunto não é simples, e te-lo que escutar em ingles, cujo os exemplos , nao são nada aplicaveis. Os exemplos deveriam ser mais direto a aplicacao de uso.Voce tem um pequeno processo,exemplo contas a pagar, aplique os conceitos em um projeto real, realmente nao gostei. grato, Mauro

When dealing with Qualifiers, I've come across exception that led me to alter the code to instead use Interfaces (Salute in the example) to abstract classes and abstract methods. If Interface is used, exception is returned (in my case by WildFly 15 server) stating Unsatisfied dependencies for type Police with qualifiers @Salute... Could be the server though. Also, the 10s intro videos before each course are annoying.

It's a bootcamp, so it starts from the very beginning. That's good. But all in all I miss testing and test classes. i.e. at least one chapter covering tests in the spirit of test-first.

I think that professor should have more code examples. However, he explain very clearly the theory. I liked it and recommend it.

The instructor details each section of CDI and explains it well. Plus he supplied working examples that can be used in creating my own CDI applications.

A great introduction to CDI. I have learned a lot with this course. You have to read CDI JSR for further details.
